20DC170A3EYNA2CNK

The Allen-Bradley 20DC170A3EYNA2CNK is an adjustable-frequency AC drive designed to enhance motor control capabilities. Designed for use with three-phase electrical systems, it operates at a nominal voltage of 400V AC while supporting a significant current rating of up to 170 amps (normal duty). It stands out with an IP20-rated enclosure that follows NEMA Type 1 standards, providing a suitable level of protection for indoor environments.

The drive's inclusion of a full numeric LCD simplifies interaction, allowing users to monitor and adjust settings more easily.

As a key safety aspect, the 20DC170A3EYNA2CNK model features an IGBT braking system, which enhances the reliability of motor operations. The drive is also outfitted with an adjustable bus undervoltage trip to protect against voltage fluctuations. Additionally, the heat sink thermistor is monitored by a microprocessor that ensures the unit does not operate under high-temperature conditions, thereby extending its lifespan.

Operational efficiency is supported by the logic control ride-thru capability, allowing the drive to maintain functionality for 0.25 seconds when not actively running. Furthermore, a power ride-thru feature enables the drive to sustain performance for up to 15 milliseconds under full load, promoting stability during power dips. This makes the 20DC170A3EYNA2CNK well-suited to demanding industrial applications requiring precise motor speed and torque control.
